PAUL G. SWARS, OF PITTSBURGH, PENNSYLVANIA, ASSIGNOR TO WESTINGHOUSE ELECTRIC & MANUFACTURING COMPANY, A CORPORATION OF PENNSYLVANIA.

TROLLEY-CONDUCTOE DEVICE.

Application filed April 16, 1923.

To aZZ whom it may concern:

Be it known that I, PAUL G. Swans, a citizen of the United States, and a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Trolley- Conductor Devices, of which the following is a specification.

My inventionrelates to trolley-conductor devices such as frogs and crossings, and particularly to renewable approach members therefor.

One object of my invention is to provide a device of the above-indicated character that shall be simple and durable in construction, economical to manufacture and effective in operation.

Another object of my invention is to provide a trolley-conductor device that shall comprise only two members at an approach end, which members may be readily assembled in operative positions by a simple tool, such as a hammer.

Another object of my invention is to provide a trolley-conductor device that shall have a body member and an approach member so co-operatively formed and related as to permit the approach member to be wedged in operative position by a relatively simple movement.

In practicing my invention, I provide a removable approach member for a frog or other trolley-conductor device, to take up the shocks and wear incident to the passage of trolley contact members, in which the frog and the approach member are formed and related to permit them to be co-operatively engaged without the aid of any other holding member and which, when the approach member is placed in proper position, will not separate so long as the trolley conductor is in its operating position.

Figure 1 of the accompanying drawing is a plan view representing a portion of a frog or other trolley-conductor device and an approach member embodying my invention;

Fig. 2 is a view, in side elevation, of the device shown in Fig. l; i

Fig. 3 is a plan view of the approach member;

Fig. 4 is a view, in side elevation, of the approach member illustrated in Fig. 3;

Fig. 5 is an end view of the same member;

Serial No. 632,183.

Fig. 6 is a plan view representing a portion of the frog;

Fig. 7 is a side view of the portion of the frog illustrated in Fig. 6;

, Fig. 8 is a view representing a vertical section of the device shown in Fig. 7 on the line VIIIVIII.

Referring to the drawings, I have shown a frog having a body member 1 provided with a channel or passage 2 for the reception of a trolley conductor 3 The body member 1 is provided with a notched or irregular recess 4, at its outer end (best shown in Fig. 7), which is adapted to receive the notched or irregularly shaped inner end of a bayonet approach member 6. The upper engaging faces 5 of the end member 5 are preferably tapered inwardly, as best shown in Fig. 5, to engage correspondingly tapered walls of the notched recess 4-. A recess 7 (see Fig. 6) is provided in the end of the body member 1 to receive an extension 8 of the approach member 6.

In order that the trolley conductor 8 may be rigidly secured in position in the ap proach member 6, I provide the approach member with lips 9 which may be bent around the trolley conductor after the parts are assembled.

In mounting the approach member, it is placed with its lips 9 over the conductor 3 in such position that its irregularly shaped, notched end portions 5 will enter the recess 4 when the approach member is moved along the conductor 3 toward the body mem ber 1. A few well directed blows against a projection 10 near the notched end of the approach member 6 will force the parts together and cause the approach member 6 to be self-locked in its proper operating or self-locking position, as illustrated in Fig. 2, due to the upward pressure of the conductor 3.

If it is desired to include additional means for locking the approach member in position and for preventing the projections or side walls 11 and 12 (see Fig. 6) 0f the body member 1, from spreading, I provide a flanged clamping plate 13 which rests upon the top of the projections 11 and 12 and is clamped thereto by means of a wing nut 14: on a stud 15 which extends through the clamping plate 13 into the upper portion of the approach member 6.

If it is desired to remove the approach member 6, the thumb nut 1a and. the clamping plate 13 should be first removed; Then, if the trolley conductor 3 is bent downwardly, it will be found that the approach member- 6 may be easily removed from its wedged-in postion between the body member 1 and the trolley conductor 3.

While I have shown and described a particular form of my invention, I desire it to be understood that changes may be eiiect ed therein without departing from its spirit and scope as set forth in the appended. claims.

I claim as my invention:

1. A trolley-conductor device comprising a conductor-receivi11g body member having a notched recess in its under side, and an approach member adapted to engage the notched recess.

2. A trolley-conductor device comprising a conductor-receiving body member provided with a notched recess in its under side, and an approach member, one-endot" which is adapted to fit into the notched recess-and be locked therein.

8. A trolley-conductor device comprising a body member and a bayonet approach member adapted to be actuated directly along the conductor into a self-locking position.

a. A trolley-conductor device comprising a. body member having a channel adapted to receive a trolley conductor and provided with a recess of irregular shape, and an approach member one end of whieh is adapted to fit into the recess and be retained therein by upward pressure of the conductor.

5. A trolley-conductor device comprising a body member and an approach member iaseaasb one end of which is adapted to wedge between the conductor andthe' body member.

6. A trolley-conductor device comprising a conductor-receiving body member having an apertured top portion and also provided with a recess of irregular form. an approach member, one-end of which is adapted to fit into the recess, and means for holding the approachmeinb'er in position and for keeping the Walls of said top portion of the body member from spreading.

7. A trolley-conductor"device comprising a body member having a channel to receive a=trolley conductor andprovided with a recess of irregular shape the upper engaging faces of which are tapered inwardly, and an approach member one end of which is provided with a portion having its faces tapered and adapted to fit into the recess.

8; A trolley-conductor device comprising a body member having a channeladapted to receive a trolley conductor and provided with a recess in its underside, and an approach member one end of which is adapted to Fit into the recess and be retained therein by upward pressure of the conductor.

9. A trolley-conductor device comprising a body member having a channel to receive a trolley'conductor and provided with a recess the upper engaging faces of which are tapered, and an approach member one end of which is provided with a portion havingits faces tapered and adapted'to fit into'the recess.

In testimony whereof, I have hereunto subscribed my name this 13th day of April, 1923.

PAUL G. SWARS.
